Does drinking Aloe Vera Juice really help in weight loss? I know it tastes nasty but I am willing to take one for the team if it helps.

I'm going to say no since the only sites that claim that are the ones that are selling it

Here is what Dr Weil has to say about Aloe Vera and Aloe Vera Juice:

Aloe vera juice, sold in all health-food stores, is intended for internal use. The main use is to help heal ulcers and other irritations of the gastrointestinal tract. In high doses, aloe is an irritant laxative, so if you want it to soothe the lining of your GI tract, you must stay below the laxative dose.
